myQSL.org is the world's largest collection of CB radio QSL cards from the 1970s. QSL cards were postcards used by radio operators to confirm contacts over the airwaves. During the CB radio craze of the 1970s they developed into a popular and creative hobby, with tens of thousands of people making, exchanging and collecting millions of cards. This collection is part of an attempt to document and preserve the hobby of CB radio QSL cards.
